JOSEPH HOFFMAN, OF NEW YORK, N. Y.

LEAD AND CRAYON HOLDER.

SPECIFICATION forming part of Letters Patent No. 223,513, dated January13, 1880.

Application filed November 4, 1879.

To all whom it may concern:

Be it known that I, J osEPH HOFFMAN, of the city, county, and State ofNew York, have invented certain new and useful Improvements in Pencil orLead and Crayon Holders, of which the following is a specification.

In Letters Patent No. 213,569 and No. 215,521 I have described and showna lead or crayon holder in which a tubular case or handle andlead-receivin g tube are combined with clamping-jaws and a means forclosing the same on the lead.

In carrying out my invention, I have generally adopted the planindicated in my Letters Patent No. 215,521, thejaws being mounted on orforming part of a longitudinally-movable lead-containing tube orreceiver, which extends through the length of the case or handle, andhas on its rear end a cap project ing from the rear end of the handle.In producing the said article in a manufacturing way, I find itconvenient in some instances, and economical in some respects as Well,to dispense with this terminal cap, and to use a portion of the handlefor the purpose, the handle being composed of sections, instead of beingmade in one piece, as formerly, and the one section having alongitudinal move ment with respect to the other section, in order toobtain that movementof the jaw-operating device and the jaws which willcause the latter to clamp or release the lead, according to thedirection of the movement.

In the accompanying drawings, Figure 1 is a side elevation of a holderembodying my improvement, and Fig. 2 is a longitudinal central sectionof the same.

In this holder the tubular sheath or handle A, instead of being onepiece, as formerly, is divided into two sections, a a. To the rearsection is attached the lead-holding tube or receiver b, which passesloosely through the front section and terminates in the spring jaws 0,provided with the swells or inclines a, acted on by the contracted frontend, (1, of the front section, a, in the usual way. The point ofjunction or meeting of thetwo sections is covered and concealed by aferrule or sleeve, e,

0, fast to the one section and fitting around the other section snugly,but not so tightly as to prevent the latter from moving back and forththerein. The sleeve is long enough to cover the joint between the twosections, no matter what may be their position relatively to oneanother. The two are capable of moving to and from one another theproper distance to permit thenozzle d to clamp or release the jaws, andthey are prevented frombecoming separated by any suitable meansas, forinstance, by a washer on the forward end of the tube 1), which brings upagainst the front of section a when the latter has moved forward farenough.

In Fig. 2 the sections are represented as separated or moved apart inthe position which they occupy when the jaws are closed. In or der toopen or release the jaws, it is only necessary to push the two sectionstogether.

I prefer to use a spiral spring, f, interposed between the two sections,as shown, and which serves to keep them apart. The spring, however, maybe dispensed with.

stances of the case, the construction and ar-.

rangement of the jaws,-and the kind of jawoperating device employed.

What I claim, and desire to secure by Let ters Patent, is-- Theherein-described improvement 011 the lead and crayon holder shown anddescribed in Letters Patent No. 215,521, the same consistingin thecombination, with thejaws and the jaw-operating devices, of a tubularsectional sheath or handle composed of two sections, the one carryingthe jaws, the other the jaw-operating device, and the two beinglongitudinally movable to and from one another, as herein shown andspecified.

In testimony whereof I have hereunto set my hand this 1st day ofNovember, A. D. 1879.

JOSEPH HOFFMAN.
